THOMAS BOND, OF BRANTFORD, ONTARIO, CANADA.

BANK GAGE.

Application filed August 18, 1923. Serial No. 658,140.

To all whom it may concern:

Be it known that I, THOMAS Bonn, a subject of the King of Great Britain, and a resident of the city of Brantford, in the county of Brant, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Bank Cages, of which the following is the specification.

My invention relates to improvements in bank cages and the object of the invention,

is to devise manually controlled means for releasing the shutter which is spring actuated into the closed position in front of the cage for protecting the. occupant from being held up by bank robbers.

A further object is to devise'improved means whereby the raising of the shutter will automatically. actuate releasing means which normally holds bullet proof side curtains for protecting the sides of the cage.

. A still further. object is to devise means whereby the springs which impel the shutter upwardly will act as buflers therefor when the shutter reaches its uppermost position. v

Another object is, to devise improved -means for resetting the shutter when it has been once actuated.

My invention consists of a bank cage constructed and arranged all as hereinafter more particularly described and illustrated.

in the accompanying drawing in which:

Fig. 1 represents a vertlcal cross sectional view of a cage looking towards the front,

showing the shutter and side curtains in the inoperative position.

Fig. 2 is a similar View to Figure 1 showing the shutter and sidecurtains 1n the operative or protectlng pos1tion.

Fig. 3 is a vertical sectlon through the line 33 Flgure 1.

Fig. 4' 1s an enlarged vertical sectlon 7 through the line 44 Figure 1.

5 is a vertical sectional detail of a portion of the actuatlng means for releasin the side curtains.

Fig. 6 isa longitudinal section of one of the side curtain houslngs broken away 1ntermediately and illustrating the means for normally holding the door thereof in posiv tion.

Like characters of reference indicate corresponding partsv in the different views.

1 is the cage provided with the usual grids 2. 3 is the shutter which is constructed of ballet resistingmaterial and is adapt- 'to be secured to the posts 5 and provided with lower vertical slots 9 and upper vertical slots 10 in the forward face of such housing.

11 and 12 are respectively upper and lower cylindrical slide blocks adapted to slide in thehousing 8, each upper block 11 provided with a forwardly directed pin 13 extending forwardly through the corresponding slot 10 and each block 12 provided with a similar pin 1 1 extending forwardly through the slot 9. 15 are springs, each secured at its upper end to the block 11 and at its lower end to the block 12. 16 is a rib on the inner face of the bottom of the shutter 3.

17 is a vertically disposed. toothed rack provided on the rear face of the shutter 3 and adapted to engage the pawl 18, pivotally connected to the forward end of the actuating lever 19 which is fulcrumed at 20 in the vertically disposed standard 21 a mounted on the floor of the cage in rear of the shutter 3. 22 is a weight actuated pawl pivotally secured in the standard 21 and adapted to engage the teeth of the rack 17. 23 is a laterally extending bar hinged to the sides of the cage 1 by thehinge 24, said bar 23 having pivotally connected to its forward face the forwardly extending rod 25, which is in' turn pivotally connected at its forward end to the lower end of the pivotally mounted dog 26 which is adapted to engage the teeth of the rack 17. 27 is a laterally extending rod journalled in the bearings 28 on the side posts 5 of the cage, said rod carrying the depending arm 29 which is pivotally connected at its lower end to the rearwardly extending rod 30 journalled in the bearing 31, the rear end of the rod 30 being provided with the actuating lever 32. 33 are brake arms secured intermediately of their length to the rod 27 and their lower ends connected by means of the chains 34 with the dogs 35 which are pivotally mounted on collars 36 on the spring receiving standards, each of said dogs having a stepped shutter engaging face. I 37 are collapsible side curtains of bullet proof material secured at their tops in the housings 38 provided with the hinged hot I shutter.

tom doors 39. 40 are eyes provided on the upper faces of the doors in the vicinity of their free edges, said eyes adapted to'be engaged by the hoohedwends of the "latches 41 which are pivotally mounted in the housings 38, the upper ends of said latchesbfeing pivotally connected to the longitudinally extending rod 42 journalled in the hou sing. 43 is a spring interposed between the rear latch 41 and the rear end ofthe casing, said s rin' bein freel mounted on the rod 42.

The forward end of the bar protrudes freely through the forward face ofthe housing. {t l-are arni-Spim'taIlymounted in recesses 45 in the side face oft'he corner posts 5, said arms normally inclined outwardly to engage the forward endsof the rod 42 and hold them in their rearniost positionwherein the latches 431 engage the eyes 450 of the The operation of my device-is as follows:

Upon the shutter being set in the position illustrated in Figure 3 and it being desired to raise the same, the bar23 is kicked by'the occupant of the cage which will push forwardth'e rods 25, thus releasing the dog 26 from the rack and allowing the shutter to be impelled upwardly by means of the springs 15. This is achieved owing to the fact that the springs have been distendedmits the rods to be forced forwardly under the influence of'the springs 4'3, releasing the latches 41 from the eyes 40 and allowing the doors 39 of the side curtain housings {to drop. This releases the curtains 37 and permits them to assume the closed position'illustrated in Figure 2 of the drawing.

After the lower edge of the shutter 3 passes up beyond the dog 35,'such dog falls forwardly, thus preventing the shutter falling again intothe open position, untilthe dog'is released.

' 'Tolower the shutter the lever 32 is pulled rearwardly' and through the medium of the pivoted arm 29 pulls rearwardly the dog 85'out of engagement withthe bottom edge of the shutter, permittingthesame to drop until'the lower edge thereof comes into engagement again with the pins.

' Simultaneously with this action, the brake i arm is thrown forwardly-by the arm 29 until its free end "engages the "rear face of the shutter, thus braiking it in its down-- ward movement.

hen it is desired to reset the shutter, the

lever 19 is actuated so that the pawl 18 en gages the teeth of the toothed rack 17 and as "thelever is lifted upwardly the shutter will be correspondingly lowered, the weighted pawl '22 preyenting'retrograde motion of the shutter as the lever is actuated in an upward direction, the leg 46 on the forward end of the lever '19 engaging the lug 47. The leg 46 prevents such pawl 22 from engaging the rack 17 when the lever is in the position illustrated in Figure3. 1 V

The side'shut ers are replaced by hand inthe housings '38 and the doors 89 elosed, the arms ll heingre's'et in engagement with the forwardrodsdQ.
